Alfred Rheinstein ATTORNEYS UnitedStates Patent- SE'I TING .SHOE FOR HOLLOW STIiUCTURAL WALL PANEL Thisinvention relates to a wall assembly device, and more particularly to amounting or setting shoe for joining adjacent hollow pre-caststructural. wallpanel sections. a

It is an object of this invention to provide-an assembly guide forbuilding a structural wall from hollowxprecast panel sections wherebyrelative movement of the panels is prevented after assembly to providereinforcement for the wall and to maintain the sections in registerduring setting of the bonding material.

Another object is to provide such device which ensures the proper'widthof vertical joints between adjacent' panel sections. 1

Another object is to provide a setting device of the above characterwhich is of sturdyinflexible unitary design. Y

Briefly this invention involves a setting shoe for span.- ning theadjacent ends of hollow preacastwall panel sections which comprises aflat elongated main body portion having at least one hollow wedge-shapedmember withits base centrally mounted on the body portion and with thepointededge of the wedge alignedtransversely relative to the bodyportion. A vertical flange isprovidecl at each end of the main bodyportion which has a straight section at its junction with the bodyportion and .:an outwardly tilted extension-having an inner beveledsurface. The wedgealso haslverticalside portions adjoining the main bodyportion. This configuration defines outwardly flared rectangularrecesses between eachwedge and each flange'oneither side of the wedgefor receiving the transverse partitions of adjacent wall panel sections.

Fig. 6 is a longitudinal section of a single wedge device inplacebetween two'adjacent wall sections;

Fig. 7 is a longitudinal section of a double wedge de vice in placebetween four adjacent wall panel sections. -One embodiment of theinvention is shown in Figs. 1 and 2. It is comprised of a setting shoestructure designated generally-by the numeral 10, being channelshaped inlongitudinal section (see Fig. 2) and having a fiat elongated web ormain body portion 11. At the ends 12, 13 of the main body portion 11 arerespective flanges 14, 15 whichhave corresponding straight base portionsor sections 16, '17 joined to the main body portion 11 in aperpendicularrelation thereto, and longitudinally and outwardly tilted extensions 18,19 adjoining said straight sections, which. are tapered or beveledtoward their outermost ends 20, 21.

Centrally "disposed between the flanges 14, 15 is a hollow wedge-shapedmember 22 which has its rectangular base 23 mounted on the top 24 of themain body 1 portion 11 softhat its pointed edge'25 "is transverselydisposed with respect .to the main body portion and lies roughlyparallel to, and midway between, the outermost ends 20,-"21 of theflanges 14,15. The wedge-shaped member 22'has a transverse generallytriangular-shaped hollow'central portion 26 opening on both sides 27,28. inclined side portions 29, 30 are integrally formed at respectiveends 31, 32 to the vertical faces 33, 34 of the rectangular'base 23 andconverge upwardly toward a common veitex '35 which forms the so-calledpointed edge 250i the wedge member 22. Thus it can be seen that theconfiguration of the wedge member 22 and the adjacent flange members 14and 15, define a pair of The invention is generally embodied in one oftwo alv ternate forms, one form having one wedge and flanges extendingupwardly from the main body portion at'either side of the wedge, and theother form having'a'pair of wedges with their bases mounted one on thetop'and the other on the underside of the main body portion in opposedrelation to one another, and a pair of flanges on either side of thewedges extending above and below the main body portion. The first formis used for merely joining two panel sections to one another, whereasthe second form is used for joining four panel sections together, all ofwhich will be described in greater detail hereinafter.

Other objects and features of this inventionwill become apparent in thefollowing specification and claim and in the drawings, in which:

Fig. 1 is a plan view of an embodiment having a single wedge;

Fig. 2 is a longitudinal section taken along lines 2-2 of Fig. 1;

Fig. 3 is a plan View of an embodiment having a pair of wedges;

1 Fig. 4 is a longitudinal section taken along lines 4-4 of Fig. 3;

Fig. 5 is a fragmentary perspective showing a double wedge device inplace of two adjacent wall panel sections;

outwardly 'fiared rectangular recesses 36 and 37 at either side-of thewedge member 22. More specifically, the inboard surfaces 38, 39 of thevertical sections 16, 17 respectively of flanges 14,15, and thecorresponding vertical faces 33, 34 on the basemember 23 define a pairof transverse rectangular grooves or channels '40 and 41 along theoppositeendportions 42 43 of the web 11. Likewise, the inboard surfaces44, '45 of. the flange extensions-18, 19 and'the-upper-faces 46, 47 ofthemclin'ed' side portions 29, 30 provide an outwardly flared I mouthfor the respective channels 46, 41 as shown in Fig; 2. I

The above described setting shoe can be integrally formed by eitherbending, machining, or casting from a suitable metal such as aluminum toprovide a lightweight and strong'device; The rectangular recesses 36 and37, as well as the dimension of the rectangular base 23 of the wedgemember22 are all dimensioned so as to snugly receive the transversepartitions of the particular wall panel sections being assembled as willbe described in greater detail below.

Another embodiment of the invention is shown in Figs. 3 and4, andisdesignated generally by the number it As shown in Fig. 4, thisembodiment has a longitudinal section resembling two devices accordingto the first embodiment previously described, placed back to back so asto resemble an I-beam having a pair of hollow wedge-shaped members 22centrally mounted on the web or main body portion 11 in opposed relationto one another. With this duplicate structure, the shape andconfiguration of the flanges 14, 15 and wedge-shaped members 22 areidentical all respects to the first embodiment. However, two pairs ofrectangular channels 40,

41 are provided in opposed relation to one another, i.e.

one pair on the top 24 of the main body, portion 11, and

the other directly opposite on the underside 49 thereof. Consequently,it is possible to'join together four ad,-

In building a structural wall from a plurality ofhollow wall panel sections 50 of a wellknown type, composed ofcementitious material pro-cast into sections as shown in Fig. 5 havingtwo opposed panels 51 and 52, inter-connected by transverse, partitions53, a pair of panel sections are put in place with a pair of their sideedges 55, 56 abutting one another so as to register a respective pair ofgrooves 57, '58 and the side channels '59, 69. Then the setting shoe isput in place across the two panel sections 50 so as to span the adjacentends thereof. For example, a setting shoe according to they firstembodiment having a. single wedge member 22 is placed at the bottom ofthe two panel sections as shown in Fig. 6 withthe wedge member 22inserted within the space between the opposed channels S9 and 60 and thebottom portions 61 of the latter transverse partitions 53 resting in therectangular channels 40, 41 respectively. As a matter of convenience andefiiciency, it may be a preferred practice to place the setting shoe 10at the desired location prior to positioning the panel sections. Thesetting shoe may be secured in place to the foundation 62 by anyconvenient means such as screws or the like (not shown), and thusvarious purposes. It first provides a means for quickly and easilyplacing the above type wall panel sections next to one another to bringtheir respective side edges into proper register so that the respectivechannels and grooves will be properly aligned with one another. Thesetting shoe is preferably nonflexible so as to rigidly maintain thecorrect alignment during the hardening of thebond material. Furthermore,the setting shoe is invisible from the outside and also provides thestructural wall with a strengthening member. Being of a lightweightme-tal, it is easily transported to the building site andeasily-positioned bythe mason or other workman assembling the wall. Inaddition, oxidation will not afprovide a means of ensuring the properlocation of the panel sections. At the top of the panel sections (seeFigs. 5 and 7), if a structural wall is'to be built using another row ofpanel sections above the first row,- then the second embodiment of thesetting shoe is employed.

The device is set in place in roughly the same manner as the onepreviously described. The bottom wedge 22 (shown in dotted lines in Fig.5) is placed between the side channels 59, and the web or main bodyportion 11 of the device spans the adjacent ends with the flanges 14, 15disposed on the opposite sides of the transverse partitions 53. Thus thewedge 22 on the top,24 of the main body portion 11 is properlypositioned with the flanges 14 and 15 to receive panel sections forinstallation of the next row. The assembly of the two rows of panelsections is shown in Fig. 7, where the upper end portions 63 of thetransverse partitions 53 of the bottom row 64 are maintained in their.proper position by the longitudinal channels 49, 41 on the underside 49of the web 11, and the bottom end portions 61 of the transversepartitions of the upper row 65 are received in the rectangular channels40, 41 at the top 24 of the web 11.

During such assembly of these wall panel sections 50, bonding material66, such as mortar or the like is placed in the grooves 57, 58 along theside edges 55, 56. Such bonding material may be either placed withinsuch grooves prior to placing thepanel sections side by side, or maybeinserted after the sections have been put in place. v

Thesetting shoe of the presentinvention thus serves feet the non-ferrousmetal to any important degree. In some applications a ferrous metal orother material may be preferred. While. two embodiments of thisinvention have been shown and described herein, it is to be understoodthat certain additions and changes can be made to the devices shownwithout departing from the scope and spirit of this invention.

I claim:

in a structural wall the combination of a plurality of hollow pre-caststructural wall panel sections each having a pair of transversepartitions defining elongated channels along opposite side faces thereofand a hollow center space therebetween all extending through the top andbottom of the panelsection, said panel sections being disposed in acommon plane with adjacent sections iri-contact with one another andtheir respective said channels in register; and setting shoes positionedacross contacting ends of adjacent panel sections, said shoes havingflat elongated main body portions disposed across said contacting ends,wedge-shaped members having their bases centrally mounted on said bodyportions with their pointed edges disposed transversely thereto, saidwedges being positioned between facing channels of said adjacent panelsections, and flange members at both ends of said body portionsvertically disposed in the center spaces of said sections adjacent saidtransverse partitions, whereby said adjacent. panel sections arepermanently maintained in alignment with one another and joining withbonding material is simplified.
